Android and App Performance


The 4G Slide's HSPA+ 21 modem, combined with its fast processor, makes for blazing Internet speeds. During tests, I got more than 5Mbps down with Ookla's Speedtest.net app. The phone also offers 802.11 b/g/n connectivity, and leverages that for Wi-Fi calling. Call quality over Wi-Fi isn't as good as cellular; I heard a noticeable background hiss, and voices sounded computerized at times. But it's a terrific backup for when you have no signal, and the feature isn't offered by any other carrier. The 4G slide also works as a tethered modem or a Wi-Fi hotspot for up to 5 devices, with the right T-Mobile service plan.
 
The 4G Slide runs Android 2.3.4 with HTC's Sense 3.0 extensions, on a Qualcomm dual-core,This will leave your shoulders free to rotate in their impact socket . 1.2GHz processor. This is roughly the same platform as in our other T-Mobile Editor's Choice, the HTC Sensation 4G ($199.99, 4 stars), and it offers similarly excellent performance. The 4G Slide did very well on our benchmarks, and Web pages, including Flash content, loaded quickly.

HTC's Sense is the best of the manufacturer Android skins,a hypodermic needle cannula on the rear floor. perfectly balancing extra features such as Facebook and Twitter integration in the contact book with a relatively non-bothersome visual identity. I didn't experience any slowdowns or stalls on my test phone during the review period.

T-Mobile has added several apps. KidZone creates a custom, locked screen with only certain applications on it, so your children have limited access to your phone. T-Mobile TV offers streaming television channels for $12.99 per month; TeleNav gives you GPS with live traffic, and Qik gives you video chat, that, well, doesn't work very well.

Multimedia
T-Mobile makes big promises for the 4G Slide's camera, calling it the "most advanced camera of any smartphone." It's an excellent camera, but some of the company's heavily touted features are just smoke and mirrors.

Let's start with the good news: When you hit the dedicated camera button, you'll get sharp 8-megapixel photos and clear, smooth 1080p high-def video at 24 frames per second. The video gets wobbly; it could use some image stabilization. But HTC has worked out the kinks that caused hiccups on our HTC Sensation phone. Still photos captured on the phone are as clear as any camera phone I've ever seen, and low-light photos are sharp,This patent infringement case relates to retractable syringe needle , with no shutter-speed blur. There's also a VGA front-facing camera for self shots.

T-Mobile advertises "zero shutter lag," but what it really means is that you can take photos before the autofocus has locked in. The trade-off, of course, is that sometimes these shots are out of focus. "ClearShot HDR" takes several photographs and combines them to prevent bright areas from washing out. But if subjects are moving, you'll get a weird ghosting effect. The phone also has a burst mode and panorama mode, which work as advertised.

This is a stellar media playback phone, as well. The phone has about 880MB of free memory, but it also comes with an 8GB MicroSD card under the back cover; our 32GB card worked fine.

The 4G Slide plays all the usual music formats through its 3.5mm headset jack, through its tinny speakers or over a Bluetooth headset. For video, it handled my 1080p HD-quality H.264 files without a problem. T-Mobile's streaming TV service is expensive at $12.99 per month, but it offers a wide range of live channels that play smoothly in full screen. I'd subscribe to Netflix instead,It's hard to beat the versatility of Plastic molding on a production line. which comes preloaded on the phone and also had no problem with clear, full-screen video over a T-Mobile 4G connection in my tests. There's only one missing piece: no way to connect an HDMI cable to view the content of your phone on your HDTV. T-Mobile promotes wireless DLNA streaming to get video onto TVs, but the TV side of that equation is often totally unusable. The phone also has an FM radio, which works when you have headphones plugged in.

Conclusions
The T-Mobile MyTouch 4G Slide takes most of the things we liked from the HTC Sensation and throws in a faster Internet connection and a hardware keyboard. Yes, it's a brick, but we like power, speed, and flexibility, and we're willing to weigh down our pockets for them.

Our previous Editor's Choice for keyboarded smartphones on T-Mobile was the T-Mobile G2 (4 stars, $99), which is slimmer and lighter, but slower and less powerful all around. We also quite like the T-Mobile Sidekick 4G,Do not use cleaners with Coated Abrasives , steel wool or thinners. but the Sidekick's youth-oriented Android skin can be very divisive. The MyTouch 4G Slide is state-of-the-art Android , and T-Mobile customers looking for a true pocket computer should pick one up immediately.
